About LineageOS

LineageOS is the most used and most trusted Custom ROM out there. It was started as CyanogenMod and known to be the first custom ROM or firmware which was able to make its way to some smartphone as pre-installed default firmware.

LineageOS is based on AOSP code and you will hardly feel a difference from stock Android. There are some third-party apps like Trebuchet, AudioFX, Clock, Dialer. Jelly, Eleven Music Player, Recorder, Snap Camera. All the apps are useful and there are no Ads in them. LineageOS comes without a Google app or GApps, you have to install them after flashing the ROM.

Due to its stability and performance, many other custom ROMs use LineageOS code as their base, some of them are Resurrection Remix and crDroid.

If you want a daily driver with good battery life and performance, then LineageOS is one of the best options for you.
